Iran risks going the same way as Iraq under Saddam Hussein in its dispute with the West over its nuclear works, Libyan leader Muammar Gaddafi said on Tuesday, adding Tehran is too weak to meet the challenges it faces alone.

"What Iran is doing is pure vanity," said Gaddafi. "If a decision is taken against Iran, it will suffer the same fate as Iraq ... Iran is no stronger than Iraq and will be unable to resist."

According to Reuters, Gaddafi said countries that chose isolation were doomed to fail. "No country will survive on its own in the future -- it will disappear," Gaddafi said. "The challenges facing Iran are greater than its ability to overcome them alone."

The Libyan leader's comments came as Bush administration intensifies its efforts to persuade the Group 5+1 to put extra pressure on Tehran as the latter fails to respond to their incentives package, PressTV reported. The five permanent members of the UN Security Council plus Germany (G5+1) will hold a conference call on Wednesday to decide the next step, US State Department spokesman Gonzalo Gallegos said Tuesday.

"If we are not going to receive a clear response, a clear message from them, we are going to have no choice but to pursue additional measures," said Gallegos. "So first we will see what happens with the rest of the day that is left in Europe, and then they will have their call tomorrow. We will see where we go from there," he added.
